Sidelights and transoms can turn a dim foyer into a bright welcome, but in Mandeville, LA, they have to do more than look good.
The Impact of Gulf Coast Conditions
The Gulf South sun is strong, the humidity is relentless, and summer storms test every seal and fastener.
Below is a practical roadmap for selecting and installing sidelights and transoms that bring in light, stand up to weather, and keep energy bills stable.
Prioritize structural integrity and code compliance up front, then refine glass specs, frame materials, and aesthetics.

Selecting Impact-resistant Glass

In our climate, low-E coatings tuned for high solar heat rejection help keep foyers from baking in the afternoon.
Dual-pane, argon-filled units with warm-edge spacers offer a reliable balance of efficiency and clarity.
Impact-rated laminated glass sandwiches a clear interlayer that holds shards in place under impact.
Privacy does not have to kill the light; textured, frosted, or micro-reeded lites scatter views while admitting brightness.
Installation Best Practices
